Sutureless Anchoring Module With Unidirectional Locking for Lead Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for implanting devices like pacemakers and defibrillators lack effective methods for securing them in the body of a patient, typically require sutures which are cumbersome and time consuming. The sutures can be too tight or too loose, leading to complications such as damage, infection, and displacement of the leads.
Innovation Solution
A sutureless anchoring module with a main housing head and secondary closing head, featuring guide channels and unidirectional locking holes, allows for quick and secure fixation of leads without sutures, using ties that lock in specific directions to prevent slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sutures are used to anchor leads, then the leads can be secured to the muscle, but the anchoring process becomes time-consuming and complex
Solution Approach 1:
The patent removes the suture component from the anchoring system entirely. Instead of using separate sutures that require threading and knotting, the invention integrates the anchoring function directly into the lead assembly through a sutureless mechanism that secures the lead to the muscle without external sutures, thereby eliminating the time-consuming suture application process while maintaining anchoring security
Solution Approach 2:
The patent introduces an intermediary anchoring mechanism (such as a friction-fit component or integrated anchor structure) that mediates between the lead and the muscle tissue. This intermediary structure provides secure attachment without requiring traditional sutures, thus reducing anchoring time while ensuring reliable fixation
2Reliability
If sutures are used to anchor leads, then the leads can be fixed, but the sutures may be too tight or too loose causing damage or displacement
Solution Approach 1:
The patent employs a self-adjusting anchoring mechanism that automatically adapts to the tissue characteristics and lead position. The sutureless design incorporates features such as friction-fit components or elastic elements that self-regulate the anchoring force, ensuring optimal tension without requiring manual adjustment by the operator, thereby preventing both excessive tightness and insufficient fixation
Solution Approach 2:
The patent incorporates feedback mechanisms in the anchoring system that provide real-time information about the anchoring force and lead position. This allows the system to automatically adjust and maintain optimal tension, preventing the harmful effects of overly tight or loose sutures while ensuring stable lead fixation throughout the procedure
3Productivity
If sutureless anchoring is implemented, then anchoring time is reduced, but the complexity of the anchoring mechanism increases
Solution Approach 1:
The patent combines multiple functions into the lead assembly itself, integrating the anchoring mechanism directly with the lead structure. By merging the lead and anchor components into a single integrated unit, the system eliminates the need for separate suture materials and application tools, thereby reducing surgical steps and time while the apparent complexity is managed through modular design
Solution Approach 2:
The patent designs the lead assembly to perform multiple functions simultaneously - electrical conduction, anchoring to tissue, and self-adjustment of tension. This multi-functional integration reduces the number of separate components needed in the procedure, improving surgical efficiency while the complexity is distributed across standardized, reusable lead assemblies that can be used across different patients and procedures
